There are more neural recommender models with different architectures such as NeuMF [1]}, NAIS [2]}, and NGCF [3]}. As reported by [4]}, MultVAE [4]} outperforms NeuMF [1]}; hence, we excluded NeuMF from our baselines. Moreover, as LOCA is built upon the autoencoder-based models, we mainly employed them as the competing models.
